Notes on types and synonyms. Phloeodromus hastatus Heller: The original description did not indicate how many types there are, but a serial number "7243" implied a single holotype, which is in accord with our examined specimen. For other names treated here, all holotypes were original clearly fixed by monotypy. All examined type materials of the above synonyms are very similar to each other except for the different patterns on their elytra. We studied specimens with different elytra pattern forms from various localities. Their identical male genitalia (Figs 54, 55) suggest that they all belong to the same species. So, we herein treat Phloeodromus sellatus Heller, Phloeodromus hastatus Heller, Crossoglossa sellatoides Jedlička, Parena fasciata var. unicolor Louwerens, and Parena sumatrana Kirschenhofer all as junior synonyms of Crossoglossa fasciata Chaudoir.

Comparisons. This species can be distinguished from all other Oriental-Australian species in subgenus Parena by the combination of the following two characters: (1) elytra yellow, with or without black patch; (2) postgenae with a pair of suborbital setae. The "unicolor" form of P. fasciata (Figs 53E, 53F) is similar to some other uniformly brown species, especially those African species of the P. stigmatica group, which also have the suborbital setae. P. fasciata is different from these African species in having the antennae completely yellow, versus apical seven antennomeres black. We provide a key for all uniformly yellowish brown species belonging to the subgenus Parena at the end of this paper. In P. fasciata, the rhombic form (Fig. 53H) is somewhat similar to P. monostigma, but differs in having elytra patch wider, extended laterally at least to interval 5, and the different position of first elytral discal pore. The melanic form (Fig. 53G) is similar to the dark form of P. africana, but differs in having suborbital setae and the elytra disc without depression. Description. Body length 6.7–8.9 mm. Dorsum reddish yellow to yellowish brown, elytra with varied black patch, a single large patch behind middle in most specimens, without a black patch in some specimens; antennae, legs, and venter yellow. Postgenae with a pair of suborbital setae; antennae extended to elytral base; labrum quadrate, apex straight or very weakly concave; mentum with a pair of short median setae. Pronotum nearly cordate, PW/PL = 1.34–1.47, wider than head, PW/HW = 1.08–1.15; widest at anterior third, slightly rounded at anterior half, more or less sinuate before posterior angles; posterior angles widely obtuse. Elytra slightly dilated to apex, surface without or with very faint isodiametric microsculpture; striae very shallowly incised, with fine puncture rows; intervals very sparsely punctate; disc without depression at basal third. Males with biseriate adhesive setae on apical two-thirds of mesotarsomere 1 and almost full length of mesotarsomeres 2 and 3. Apex of abdominal sternite VII clearly emarginate in males (Fig. 8I). Median lobe of aedeagus slender (AL/AW = 4.8–5.7), ventral margin gradually curved; apical third more or less bent to right side; apical lamella nearly ovate, LL subequal to LW, apex rounded, weakly bent upward in lateral view. Endophallus with primary sclerite small and linear, about one-seventh length of median lobe, with indistinct flared basal expansion; apical flagellum very short, ending near basal third of median lobe; apical sclerite widely V-shaped, well chitinized, basal core indistinct; basal sheath very small, dorsally surrounding apical half of primary sclerite; apical sheath simple, finely scaled; squamate sac not or partly divided, in similar size as basal sheath, right to squamate sheath. Gonocoxite II of ovipositor nearly quadrate, slightly wider than length, apex slightly concave, slightly projected near inner apical angle, with three ensiform setae on inner apical angle, two or three on outer apical angle. Distribution (Map 9, blue). Australia, Papua New Guinea, Sulawesi, Maluku, Timor, Java, Sumatra, the Philippines, Vietnam, Thailand, China (Taiwan, Hainan, Zhejiang). Variation. P. fasciata is widely distributed through Southeast Asia and the north part of Australasia. Its elytra color is highly varied, as might be expected with such a distribution. Generally, the following seven color forms can be recognized, but with intermediate specimens also seen. In the citations of examined materials above, we recorded the color form of each specimen by abbreviation in brackets. (1) The "fasciata" form [f] (Fig. 53A): elytra with a transverse black patch. Type of P. fasciata belongs to this form. Most specimens from regions eastern to the Wallace’s line are of the typical "fasciata" form, which has a very large black patch near elytral mid-length. A few specimens from Java and the Philippines also have the "fasciata" form, but the patch is usually shorter than in typical specimens. (2) The "sellata" form [s] (Figs 53B, 53D): elytra with a triangular black patch. Types of P. sellata, P. sellatoides and P. sumatrana all have this form. It is the most common form in regions west of Wallace’s line, but not found in regions east of that line. (3) The "unicolor" form [u] (Figs 53E, 53F): elytra unicolorous, without a black patch. Type of P. unicolor belongs to this form. The "unicolor" form occurs in Java and Timor, and is relatively common in Javan populations. (4) The rhombic form [r] (Fig. 53H): elytra with a narrow rhombic black patch. This form occurs in Vietnam, the Philippines and Java at a low frequency. (5) The "hastata" form [h] (Fig. 53C): elytra black patch with anterior margin notched. Type of P. hastata has this form. The "hastata" form occurs in Java and the Philippines at a low frequency. (6) The melanic form [m] (Fig. 53G): elytral black patch very large, with only a narrow apical region brown. This form was found in only one specimen from Papua New Guinea and is very similar to another species, P. africana. (7) The trident form [t] (Fig. 53I): elytra with trident black patch. This form was found in only one specimen from the Philippines.Published as part of Shi, Hongliang & Liang, Hongbin, 2023, Taxonomic revision of the genus Parena Motschulsky, 1860 (Coleoptera, Carabidae, Lebiini, Metallicina), pp. 1-144 in Zootaxa 5286 (1) on pages 90-94, DOI: 10.11646/zootaxa.5286.1.1, http://zenodo.org/record/795893
